DETACHABLE WATCH FOB MOTOR-DRIVEN VEHICLES.

Specification of Letters Patent.

Patented Mar. 20, 1916.

Application filed March 25, 1916. Serial No. 86,666.

To all whom it may concern Be it known that 1, CHARLES SoHInBnL, acitizen of the United States, residing at VJatertown, county ofJefferson, and State of lVisconsin, have invented new and usefulImprovements in Detachable Watches for Motor-Driven Vehicles, of whichthe following is a specification.

My invention relates to improvements in detachable watches for motordriven vehicles.

The object of my invention is to provide means for securely clamping thewatch to the steering wheel of a motor driven vehicle in such a mannerthat it can be readily detached and removed with the clamping mechanism,the watch case being permanently 1 connected with one of the clampingmembers.

In the drawings- 7 Figure '1 is a fragmentary view of the steering wheelof a motor driven vehicle showing a watch embodying my invention clampedtoone of the spokes thereof.

Fig. 2 is a rear view of the watch, detached from the spoke of thesteering wheel and showing the clamping mechanism partially in releasingposition.

Fig 3 is a horizontal sectional viewof a portion of the watch casing andclamplng mechanism, showing the clamping members in clamping position,said section being taken on a plane exposing the clamping bolts orscrews. a

Like parts are identified by the same reference characters throughoutthe several views.

The watch 1 may be of any ordinary construction except that the backwall 2 is rigidly connected at 3 with a clamping plate 4. The centralportion 3 of the clamping plate 1 is formed to fit the surface of thewatch casing at the center of the back 2 thereof, and is rigidly andpermanently secured to the back 2, by brazing, welding or in any othersuitable manner. Between this middle portion 3 and the end portions 5,the clamping plate t is bent outwardly or ofiset from the back 2 of thewatch casing, to provide 1 ample clearance for the heads 6 of theAcooperating clamping member 9 is pivotally connected at oneend of oneof the clamping bolts 7, and the other end portion provided with a keyslot notch 11, extendlng inwardly from one side, and terminating in arounded recess 12, adapted to receive the other clamping bolt 7. Beyondthe slot 11, this clamping member is extended to form a lever arm orhandle 15, which may be of any suitable contour adapted to facilitatethe manipulation of this clamping member. The slot 11 is of such widthas to permit an adjustment of the clamping member 9 to a position withthe bolt 7 engaged in recess 12. The slot is narrowed at 13 so thatforce will be necessary in order to move this clamping member to eitherclamping or releasing position, the bolt binding upon the walls of theslot when passing the converging or inwardly extending marginal portion13. Each of the clamping bolts 7, 7 is provided with a nut 18, and alock washer 19 is interposed between each of the nuts 18 and theclamping members. These washers are formed of resilient material and arebent into such form that they will engage resiliently against theclamping member 9 and against the inner faces of the nuts 18. The outerends of the bolts 7 7, are preferably provided with heads 20 to preventthe nuts from becoming accidentally disengaged and lost. These heads 20,however, are preferably removable, being provided with threaded shanks21 engaging in the threaded sockets in the bolts 7, (or 7). The middleportion of the clamping plate 9, is provided with a transverse band 25,preferably nonmetallic, and which is adapted to bear upon the spoke 26of the steering Wheel to which the Watch is to be clamped. The band isloose on the clamping member 9, and is adapted to revolve thereon, whenthe clamping member 9 is being swung toward or away from clampingposition. Both of the clamping members a and 9, being preferably formedof resilient material, and the band 25 being adapted to revolve on themember 9, it is obvious that there will be no danger of marring thesurface of the spoke or other support to which the watch is clamped.

To apply the watch to the steering wheel, the clamping member 9 isadjusted to releasing position, and the watch is then placed against thefront side of the spoke 26, in

the position in which it is illustrated in Fig. 1, after which, theclamping member 9 is swung upon its pivotal connection with the bolt 7,into clamping position, sufficient pressure being applied to the handleextension 15, to force this clamping member between the lock washer 19,and the opposing surface of the lining member 8, through the end ofwhich the bolt 7 preferably passes. When the clamping member has beenmoved to the position in which the bolt? is received in the enlargedrecess 12, the spoke 26 will be securely clamped between the band 25 andthe opposing central. portion of the lining member 8. The contour of thecentral portion of the clamping members 4 and 9, will, of course,conform substantially to the contour of the spoke 26 at the point wherethe clamping members engage it. After the clamping member 9 is inclamping position, the nuts 18 may be turned up on the bolts 7 7 foradditional security, if desired, but ordinarily this will not be necessary, particularly if the clamping member 9 is swung downwardly intolocking position, as will be the case if the slot 11 is formed to extendinwardly from the lower edge margin, as shown in the drawings. It will,of course, be understood that the clamping members are shown in invertedposition in Fig. 2. Clamping member 9 is formed of resilient material.Therefore it may be swung into and out of clamping position withreference to the spoke 26. When it is desired to remove the watch fromthe steering wheel, it is therefore merely necessary to grasp the handle15 and lift the clamping lever to releasing position, the watch being,in the mean time, supported by the other hand. It is therefore obviousthat the watch may be instantly removed and almost as quickly reattachedto the spoke of the wheel, or to any other support to which the clampingmembers may be adapted to engage.

The clamping member l may be secured to the watch casing by any suitablemeans, whether by brazing or riveting. It will, of

course, be understood that a specially constructed watch casing will beemployed, or, at least, that the back portion 2 thereof will bespecially constructed and rigidly attached to the clamping member. Iconsider this feature of my invention very important to the success ofthe device, since there is no possibility that the watch may becomedisengaged accidentally.
